Chapter 2.3


Vocabulary


Liquefaction: It occurs when an earthquake's tremors turns moist, soft, loose soil into liquid mud
Aftershock: An earthquake that happens after a larger earthquake
Tsunami: Wave(s) that bunch up into a big wave created by an earthquake
Base-Isolation: A building that is designed to reduce the energy of an earthquake to not destroy the building

Outline


  • damage caused by earthquakes
    • Soil Condition
      • Harder, packed ground will not shake as severely
      • Soft, loose soil will shake severely
    • Liquefaction
      • Worst place to build if you live where it liquefies, a hill, or a sloped area
    • Aftershocks
      • If a building has weakened after a major earthquake, an aftershock can cause the building to fall
    • Tsunami(s)
  • Safer building structure
    • Safer Area
      • Build buildings far away from known active faults
      • Anchor building to ground if area is known to liquefy
    • Construction methods
      • Base-Isolation Building
        • Base Isolation bearings are used for this design
      • Helpful things
        • Metal connectors can be use to make frames stronger
      • Protecting Yourself During an Earthquake
        • If an earthquake happens while inside a building, go for a table or chair
          • If none, crouch near inner wall
        • If an earthquake happens while outside, go for an open area
        • Always make sure you have an earthquake kit
